    Installing some auxiliary LED lights around the bed of the truck. Only want them to be on when something happens (like you unlock the doors or open a door). Thought the dome light would be a good source since it is timed. LED's are really low voltage so I think this would work fine.

    Anyone know where to pick this circuit up without having to do it in the headliner itself?

    Why do you want them tied to the dome light?? Are they for looks or for lighting in the bed??

    There was a write up a few weeks back about a bed light install...Complete with a switch in the bed to turn them on and off.

    I mostly use my truck for my 13 yr. old travel baseball team. The bed lights are for loading and unloading baseball gear in dark ballpark parking lots. I thought of putting a switch in so that when the tailgate drops, they come on but my dorky group of 13 year olds will leave the bed down for hours at the ballpark. I am really looking for a solution "somewhere in the middle" between always on when the tailgate is down and only on when door is open or dome light is on.

    Guess I am trying to err on the side of too little. Suggestions are welcome from you guys!

    I tried running my bed lights in series-parallel with the map lights so that the bed lights came on when I clicked the map light on the overhead console. I cut the ground side of the switch wire and ran that side to the bed lights. It worked but the LED map lights and the bed LEDs were pretty dim. The Map LED drops enough that it affects the brightness of the bed LEDs.

    I also tried running the map lights through the ground of a relay so it would apply power to the bed lights when I switched on the map light but there wasn't enough current to trip the relay I had. The map light would come on but the relay wouldn't trip. Also, the wire going up to the lights is pretty thin so it'll limit how much current you can pump through there. The relay method would be the best way if you can get it to work. However, tying them to the interior light will cause your bed lights to come on whenever you open your door.

    I wound up just putting a switch in the compartment by your left knee and hooking it up to an accessory circuit (requires the keys in the ignition to turn on the lights). The switch is hidden when the door is closed so you're not likely to accidently turn it on and hooking it to the accessory circuit ensures they won't remain on if I take the keys out.
